The challenge is a seven-day meal plan that focuses on whole foods and emphasizes lean protein and lots of fruits and vegetables.

2.There are also plenty of other popular "detox" programs and healthy eating challenges out there that you might want to try. Just make sure to do your research first, and know what your goals and expectations are going in.

Lots of people will do some kind of "detox" or healthy eating challenge in January. These aren't for everybody, but if you want to do one, make sure to do plenty of research first. Some of the most popular programs are the 21-Day Sugar Detox, Whole30, and the 21-Day Fix. Before you start anything, you should do lots of research, and talk to a doctor or nutritionist if you have concerns or existing food or medical issues.

Also, programs like these can be useful for jump-starting a healthier year and making you feel more energetic, but no monthlong program will lead to immediate, substantial weight loss. If your goal is to lose fat, you'll have to commit to a lifestyle change that goes beyond whatever program you try.
